Abstract
The utility model relates to a dust-absorption blackboard brush, which consists of a brushing handle, a dust-absorption box, a base, an iron wire net, a cotton cloth and a dust-absorption electric mechanism. The utility model is characterized in that the dust-absorption motor is arranged at the middle art of the base, which is a dust-absorption blackboard brush having the practical value.
Description
The utility model relates to dust absorption blackboard eraser.Belong to operation Department of Transportation by International Patent Classification (IPC) (IPC) division, printing branch is write or drawing appliance; The big class of office appliance is write or drawing article; The assistant product group of writing or draw, big group of the cleaning device of blackboard or slabstone has the little technical group field of sucking chalk powder device.Classification number is B43L21/02.
At present, have now and big group of the cleaning device that once had, have the technology of sucking chalk powder device that the demand of dust absorption blackboard eraser was all done very fruitful effort, also once designed many outstanding technical schemes about blackboard or slabstone.As being declared by Zhao Yumin of the Decree of Patent Office of China in 1996, Granted publication number is CN2230239Y, and China Patent No. (ZL) is: No. 95214279.1 utility model title is the utility model patent of " holding the dirt blackboard eraser ", the technical scheme that is adopted.Big group of the cleaning device of blackboard or slabstone, it is a routine of great value invention that sucking chalk powder device technique aspect is arranged, and it has solved the problem of blackboard eraser effectively.But still have some deficits the problem that the chalk dust that its also very difficult solution falls when erasing the board pollutes air.
The purpose of this utility model is to provide a kind of dust absorption blackboard eraser.The problem that the chalk dust that falls when erasing the board to separate pollutes air.
The purpose of this utility model is achieved in that the dust absorption blackboard eraser of this utility model.Mainly constitute by wiping handle, dust-absorbing box, base, wire netting, cotton, dust suction motor.Its wire netting, cotton, dust suction motor are by selecting for use on the market.Its wiping handle is a staff-like shape, uses plastic material, through the injection moulding processing and manufacturing.Its dust-absorbing box, base are rectangular shapes, use plastic material, through the injection moulding processing and manufacturing.Wipe handle and adopt the method for attachment of commentaries on classics ball to be installed in the medium position of base, constitute stock shape syndeton, function has been the handle effect.Dust-absorbing box adopts pipe connecting method to be installed in the medium position of base, constitutes the tubular form welding structure, and function has been to collect the dust effect.Cotton adopts series-mounting to be installed in the position, both sides of wire netting, constitutes series connection structure, and function has been the effect of erasing the board.Wire netting adopts nesting method to be installed in the lower position of base, constitutes the rectangular shape nested structure, and function has been that the supporting dust is by effect.The dust suction motor adopts the screw method of attachment to be installed in the medium position of base, constitutes syndeton, and function has been the wind-force effect that dust suction is provided.So just realized the purpose of this utility model.
The advantage of utility model: big group of the cleaning device of the utility model and original blackboard or slabstone has the sucking chalk powder device technique to compare two advantages and improvement;
The first, because the utility model has designed the dust suction motor in technical scheme, so can sop up the chalk dust that falls down when erasing the board;
The second, because the utility model has designed dust-absorbing box in technical scheme, do not outwell so chalk dust can be gathered up; Thereby just can more effectively solve the problem that the chalk dust that falls when erasing the board pollutes air.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the main TV structure schematic diagram of dust absorption blackboard eraser of the present utility model;
The numbering of parts explanation in the schematic diagram: 1 wipes handle 2 dust-absorbing box 3 bases 4 wire nettings 5 cottons 6 dust suction motor
In the optimum implementation of dust absorption blackboard eraser of the present utility model, its technical scheme is achieved in that and below in conjunction with accompanying drawing the utility model is described further:
Its static structure: as shown in the figure, dust absorption blackboard eraser of the present utility model.Mainly constitute by wiping handle 1, dust-absorbing box 2, base 3, wire netting 4, cotton 5, dust suction motor 6.Wipe handle 1 and adopt the method for attachment of commentaries on classics ball to be installed in the medium position of base 3, constitute stock shape syndeton, function has been the handle effect.Dust-absorbing box 2 adopts pipe connecting method to be installed in the medium position of base 3, constitutes the tubular form welding structure, and function has been to collect the dust effect.Cotton 5 adopts series-mounting to be installed in the position, both sides of wire netting 4, constitutes series connection structure, and function has been the effect of erasing the board.Wire netting 4 adopts nesting method to be installed in the lower position of base 3, constitutes the rectangular shape nested structure, and function has been that the supporting dust is by effect.Dust suction motor 6 adopts the screw method of attachment to be installed in the medium position of base 3, constitutes syndeton, and function has been the wind-force effect that dust suction is provided.
Its dynamic structure: in force:
Its dust suction motor 6 acts on cotton 5 by wire netting 4, thereby finishes the task of dust suction.Its dust suction motor 6 acts on dust-absorbing box 2, thereby finishes the task of collecting dust.So just realized the purpose of this utility model.Thereby just can solve the problem that the chalk dust that falls when erasing the board pollutes air.
Below by using method, the utility model is done more detailed description:
The dust absorption blackboard eraser of this utility model is work like this:
In use, when erasing the board, the wind-force of dust suction motor 6 is drawn onto 2 li of dust-absorbing box with chalk dust, and its dust suction motor 6 acts on cotton 5 by wire netting 4, thereby finishes the task of dust suction.
In use, when the time of falling the dust, turn on the end cap of dust-absorbing box 2 and can outwell, its dust suction motor 6 acts on dust-absorbing box 2, thereby finishes the task of collecting dust.
Realize that preferred plan of the present utility model is is material with plastics, utilize the basic equipment of stationery factory, take assembling to produce by batch, the demand with supply educational circles so just can realize practical value of the present utility model and economic worth better.
